Part of the Furniture
@dave14305 you are a smart dude. Running 386.1 Beta 1 on the RT-AX58U, I clicked through the menus without selecting Adaptive QoS and the router appears stable.
I just reflashed 386.1 B1. I dont need or use QOS so will just avoid that tab. Other then that the AX58U is working as expected with the new build.
